Method to Remove Organic Chloride from Crude Oil

There are two kinds of chlorides in crude oil, one is inorganic chlorides, i.e., inorganic salt and the other is organic chloride. It is known that inorganic chlorides such as NaCl, MgCl2, CaCl2, etc. in crude oil can cause equipment corrosion and clogging of ammonium chloride, it can be removed by electric desalting before atmospheric distillation.There are mainly two types of organic chlorine compounds in crude oil, one type is the naturally occurring as the inherent components of crude oil , while another type is artificially added as the foreign matter during crude oil exploitation , transportation and refining . These organic chlorides tend to convert into hydrogen chloride (HCl) during the crude oil refining process such as distillation, FCC, hydrogenation, delayed coking, etc. Then, this HCl dissolved into a tiny amount of water to form a dilute hydrochloric acid solution, which, in turn, results in a serious corrosion to the top section of the distillation column and overhead condensing system. The hazards caused by organic chlorides in refineries was mainly ammonium chloride clogging and the corrosion to equipments, involving primary processing and secondary processing units.


Organic chlorides are not easily removed by conventional methods, and the content of organic chlorides in crude oil hardly decreases after desalination.The existence of organic chlorides will cause great safety hidden trouble to refining and chemical enterprises. Without changing any process in the refinery, this high organic chlorides problem can be solved by adding our agent into crude oil before electric desalting. With the presence of Crude Oil Dechlorine Agent or called Crude Oil Organic Chloride Transfer Agent, chlorine element from organic chlorides could be transferred to water phase by molecular interaction to achieve an effective removal of organic chlorides. The product applies to all types of crude oil for organic chlorides removal. 


Our crude oil organic chloride transfer agent has been used in many oil refineries at home and abroad. The removal efficiency of organic chlorides is high and the operation is simple. Our products are well received by our customers.
